I was cleaning my M&P15, and was using some Outers Nitro Solvent to get the carbon off the back of my bolt. Some overspray got onto my Bolt Carrier and I didn't really think anything about it. But when I got to cleaning the BC, I noticed the overspray had taken part of the black coating off the parts. Im assuming with wear, it would come off anyway, and it always stays oiled. But will this cause any problems ?
